OVERVIEW STANDARDS
Australian Pipeline Valve (APV) standards comply with technical specification API-6A. The description for APV equipment consists of a general description, working pressure, temperature rating material class rating, product specification level (PSL) and performance requirement (PR). These ratings are defined in the following API-6A tables.
To comply with API-6A, APV offers: Pressure ratings in psi: 2000, 3000, 5000, 10,000 & 15,000. Temperature ratings: L, P, R, S, T, U, V, X & Y. Material class: AA, BB, CC, DD, EE, FF & HH. Product specification level: 1, 2, 3 & 4 (PSL 1, 2, 3, 4) Performance requirement: 1 & 2.

PSL Material Control is found in API Specification 6A, Specification for Wellhead and Christmas Tree Equipment Section 400
There are two Performance Requirement Levels, PR1 and PR2. The latter represents more rigorous performance requirements. See API Specification 6A, Section 300 and Section 900.
Section 905 covers valves (905.3 - Flowline Valves, 9.5.5 - Actuated Valves).

TRIM TYPE
STANDARD TRIM
For essentially non corrosive liquids or gases. Typical are crude and reined oils, natural or refined gases and processed hydrocarbons. Typical uses are wellheads, manifolds flowlines, and other similar installations requiring a through conduit valve. The temperature limitations are 0º to 250ºF (-17.7ºC to 121ºC).
STAINLESS TRIM
For substantially the same service as T-21 but where the corrosion resistance of 13% Chrome Stainless Steel internal parts are desirable. Also usable for mildly corrosive fluids and gases where limited corrosion of the internal body surfaces can be tolerated. The temperature limitations are 0º to 250ºF (-17ºC to 121ºC). Recommended when partial pressure of CO2 is greater than 7.3.
FULL STAINLESS STEEL TRIM
For any liquid or gaseous product for which the resistance of the 13% Chrome Stainless is adequate. Also used where the resistance of Stainless Steel is desirable from the standpoint of product purity. The temperature limitations are 0º to 250ºF (-17.7ºC to 121ºC). Recommended when partial pressure of CO2 is greater than 30.
SOUR GAS & OIL
Primarily for sour gas and oil where resistance to Hydrogen Sulfide embrittlement is required. Also suitable for other chemicals, products or hydrocarbons when H2S is present. May be used when CO2 is present in smaller amount then H2S. The temperature limitations are 0º to 250ºF (-17.7ºC to 121ºC).
STAINLESS SOUR GAS AND OIL TRIM
Primarily for sour gas and oil when the CO2 exceeds the H2S content. It is intended to provide resistance to the metal loss type of corrosion usually associated with CO2, plus resistance to Hydrogen Sulphide embrittlement. The temperature limitations are 0º to 250ºF (-17.7ºC to 121ºC).
WATERFLOW (UNINHIBITED)
Primarily for use in untreated or uninhibited brackish saline water typically associated with oilfield waterflood projects and/or disposal wells in which the internal plastic coating of the body surfaces provides resistance to salt water corrosion. The internal parts are also resistant to Sulfide embrittlement and corrosion. The temperature limitation are 0º to 250ºF (-17.7ºC to 121ºC).
LOW TEMPERATURE – STANDARD TRIM – GENERAL OILFIELD
For essentially non-corrosive liquids or gases. Typical examples are crude and refined oils, natural or refined gases and processed hydrocarbons. Typical uses are wellheads, manifolds, flowlines and other similar installations requiring a through conduit valve. The temperature limitations are -50º to 180ºF. (-45ºC to 82ºC).
LOW TEMPERATURE – SOUR GAS AND OIL
Primarily for sour gas and oil where resistance to Hydrogen Sulphide embrittlement is required. Also suitable for other chemicals, products or hydrocarbons where H2S is present. May be used when CO2 is present in smaller amounts than H2S. The temperature liitations are -50ºC to 180º F (-45ºC to 82ºC).
